Frequently Ask Questions

  1. Q. What is a storage battery?
    A. A reservoir which may be used repeatedly for storring energy. Energy is put into it and removed from it in the form of electricity, but it is stored as chemical energy.

  2. Q. What are volts?
    A. Units of force or pressure of electric current. In an industrial truck, running speed and lifting speed are dependent upon battery voltage. The voltage of a battery depends on the number of cells. Each lead-acid cell has 2 volts; a 16-cell battery has 32 volts and an 18-cell battery has 36 volts.

  3. Q. What is ampere hour (A.H.) capacity?
    A. Product of amps multiplied by time. It refers to the volume of electricity that can be drawn from a battery. Other factors (refers to number of cells in battery, truck resistance, truck motor, rate of discharge, etc.) being equal, higher ampere hour capacity batteries will run a truck longer than those with lower ampere hour capacities. A.H. capacity of a battery dependes on the type, number, and size of plates per cell.

  4. Q. What is meant by capacity "at the six-hour rate"?
    A. The amount of electricity which a battery yields varies with the rate at which the electricity is taken out. For example, an 18 E85-17 Ironclad battery is rated at 680 ampere hours at the six-hour rate. This means that this battery will deliver a total of 680 ampere hours if it is discharged at a continuous rate of 113 amperes per hour for six hours. However, if this same battery is discharged at a lower rate, such as 90.5 amperes per hour for 8 hours, it will deliver a total of 724 ampere hours. The lower the rate of discharge permits the battery to yield more current before it drops below a useful voltage.

  5. Q. What is electrolyte?
    A. Electrolyte is the mixture of sulphuric acid and water in a lead-acid battery. The operation of the battery is affected by the specific gravity, quantity, purity, etc., of the electrlyte within the cell. It is the weight of the acid-water mixture compared to the weight of an equal volume of water. Pure water has a specific gravity of 1.000. Concentrated sulphuric acid has a specific gravity of 1.835. Specific gravity of battery electrolyte in an industrial truck battery is normally from 1.280 - 1.315 when fully charged and 1.110 when fully discharged.

  6. Q. What is a sealed battery?
    A. Sealed batteries are really Valve Regulated Lead Acid, which mean that after they are manufacture they can't be opened; when the battery charge and discharge it recombine in the gassing process. They are also commonly known as Sealed Maintenance Free because you don't have to water the battery. Other feature is that the electrolyte will not leak out. There are two technologies that make this possible:
    • AGM - The electrolyte is fixed in a glass mat (AGM). They are excellent high current capacity and especially economical.
    • Gel - The electrolyte is fixed in a gel-like substance (dryfit technology). Highest reliability and long life, particularly suitable for cyclic applications.
